Advantages of the Rotatech wheel cutting system At least 30%-50% faster-cutting speed than factory designs. Operating cost is the lowest in the Industry. Cut your annual teeth cost by 50% or more. Eliminate frustrating teeth changing. You can plunge cut or slew cut with the same tooth. The teeth are massive, to reduce broken teeth from exiting the wheel. No bolts are in harm's way! No pockets in harm's way or take power away from cutting speed! Fast teeth changing 1 minute per tooth. Super smooth cutting because of high tolerance machined wheel and components. Less stress on the machine frame because of smooth cutting. Less maintenance on pillow block bearings, drive belts, and sheaves. Teeth can be re-sharpened or re-tipped. More economical to operate because of fewer teeth usage. Wheel cost is ½ the cost of other aftermarket designs. Faster cutting in hardwoods than Green Teeth, Sandvik, Pro teeth, Super Teeth, Yellow jackets, and many others. If you fit all of your grinders with this wheel, you will be able to interchange all components (teeth, keeper blocks, bolts, and nuts). That is a great advantage if you are short teeth on one machine, you can take teeth from a different machine until you get more teeth or parts ordered. No cutter system today is machined to tighter tolerances and has the best combination of shear and strength with engineering to reduce the power needed to get stumps done fast.
